Answer 1

Using bs4 4.7.1.
There is only one table and you want the second column (td) of the last row. You can use last:child to select the last row; which should be used in conjunction with tbody type selector, and > child combinator, so as not to get header row. You can use nth-of-type to specify the td cell to return.
Now you may wish to develop this in at least two ways:
Handle cases where not found e.g.
name = getattr(soup.select_one('title'), 'text', 'N/A')
timing = getattr(soup.select_one('tbody > tr:last-child td:nth-of-type(2)'), 'text', 'N/A')
Add items to lists/data structure, which can be output as a dataframe at end and written out as csv. Or you may wish to stick with your current method
Python:
import requests
from bs4 import BeautifulSoup as bs
urls = ['https://racevietnam.com/runner/buiducninh/ecopark-marathon-2019', 'https://racevietnam.com/runner/drtungnguyen83/ecopark-marathon-2019']
with requests.Session() as s:
for url in urls:
r = s.get(url)
soup = bs(r.content, 'lxml')
name = soup.select_one('title').text
timing = soup.select_one('tbody > tr:last-child td:nth-of-type(2)').text
print(name, timing)

Answer 2

This is my code.
It's working Ok.
import requests
from bs4 import BeautifulSoup
f = open("input.ecopark","r")
f_content = f.readlines()
f.close()
for url in f_content:
r = requests.get(url.rstrip())
soup = BeautifulSoup(r.text, 'html.parser')
result = soup.select("table tbody tr td")
x = ""
for i in result:
if not x:
if i.get_text() == "Finish":
x = 1
continue
if x:
print(url.rstrip()+ " "+i.get_text())
break
